We wrote about photographer Seth Casteel’s diving dogs back in March — and we’re thrilled to learn he has a coffee-table book of his pawesome photos. Underwater Dogs contains more than 80 portraits, many of which can be found only in the book.

Seth was kind enough to send us a bunch of the photos and a copy of the book, which we’ll give to one lucky Dogster reader. You can also see more of his amazing work on his Facebook page.
